Lattels Patent No. 110,856, dated January 10, 1871.

IMPROVEMENT IN DEVICES For: SECURING THE FINES or HAV-TEDDERS.

The Schedule refund to in these Letters Patent and making part of the same.

.To all whom it may concern Be it known that I, DELAncY' KENNEDY, of the city, county, and State of ,N cw York, have invented a new and useful Improvement in Clamping Devices.

for the Tincs of Hz y-Tedilers or Spreaders, of which the following is a full, clear, and exact'description, reference being had to the accompanying drawing form-' ing a part o'fthis specification, and in wliicli-' Figure '1 represents aview in perspective of the bar of a hay-tedder fork, in part, with, my improvement for holding the tines to their places applied thereto; Figure 2 is a face view'of one of-thc clamps or buttons by which the tines are secured; and

Figure 3, a transverse section through the bar, with the tines and clamping devices in their places-thereon. Similar letters of reference indicate 'correspondin g My invention has reference to a mode of fastening the tines to the bars of the forks of a hay-tedder or spreader, and providing for the removalof the same when required, substantially as described in Letters Patent of 'thc'Unitcd States (No. 80,412) issued to me July 28,

1868, and in which the upper parts of the tines of the fork, after being coiled around a transverse stud in the lower end of the bar, have their terminal portions extended beyond the coils, and the extremities of such terminal portions bent to enter holes inthe bar, wherethey are retained by overlapping flanges on buttons or clan'|ps,-,which are secured upon each side of the arm by a'bolt passing through them and the bar, said buttons or clamps having a portion of their overlapping flanges cut away so that there is one position to winch it they are turned they will not retain the tines; which allows of the removal of one or both of the tines on opposite sides of the bar, for the insertion of new tines, or for any other purpose that may be necessary. I

This invention consists in a grooved construction of the buttons or clamps on the inside faces of their overlapping flanges, whereby they are made to receive within them the terminalportions or inner extensions of fthe tines, and are thereby locked or preven ted from shifting or turning when set .to hold the tines, and

whereby the terminal portions of the tines are braced.

Referring to the accompanying drawing- Arcprcsents one-of the bars, in part,of a hay-ted der fork; and

-B B, the rear or upper portions of the tines, coiled to fit the ends of a transverse stud, b, in the lowerend 'of the. bar A, but not fixedly attached thereto; aiid .having their terminal. portions i: extended beyond the. coils in what may be termed an npward'direc'tion, and the extremities of such terminal portions bent as at d, which bent portions enter holes in the bar, where they are retained by the overlapping flanges of the buttons or clamps C G, secured upon each side of the. arm by a bolt, D, passing through them and the bar;

These clamps are cut away for a portion of their flanges, as at c, to facilitate, by suitably turning them,

i the insertion and removal of the tines ashereinbefoic referred to. g

The one (C) of them may be fitted loosely on the bolt D; but the other (0) be arranged to screw thereon, and answering in the place of a nut, although an additional lock-nut may, if desired, be used to hold the clamps to their grip on the terminal portions of. the tines.

To prevent said buttons or clamps G C from being turned accidentally or working so as to bring the cutaway portion 0 of them into its uncovering position of the tines, said clamps are formed with grooves, f, on the. inside faces of their overlapping flanges, which groo'vcs serve to receive within them the terminal portions 0 of the tines, thereby locking the clamp from turning, and bracing said portions of the. tines. These grooves may either. be single or there may be a series of them,running at suitable angles, the one into the other, as represented in lig.-2, to allow of thc lock of the clamp on the tines in dilfereut ooiiti nsef the former, to'suit dihe'rent thicknesses-of tines, or as other circumstances may require.

That is here claimed, and desired to be secured by Letters Patent, is-- The grooves f in the. buttons or clamps O O, in

combination with the terminal portions c of the tines, substantially as specified.
